Question

Hello i was wondering if someone could help me verify my answer.For
the circuit below, we are suppose to find the values ofdi(0)/dt,
before the switch is closed, and then find (i)t when t>0. We are
given that Vc(0) = 20V and i(0)=0A.
For both of the unknowns i got 0 amps and I determined that it
wasan under-damped response. is this correct or wrong??
